' To all whom it may concern,.-

Beit known that I, CLARKE. GARDNER, a citizen of the United States, residing at Osage, in the county of Mitchell and State of Iowa, have invented certain new and useful Improvements in Clips, of which the followin is a specification. f

y invention relates to clips, and es ecially to .that class "of clips ada ted for ho dxo in together paper sheets and t e like.

he object o my invention is to provide a clip made of sheetmetal covered on one side with a coating of adhesive adaptedfor adhesion `topapers and the like, and to be bent I or folded to retain the papers in position.

It, is Well known that difficulty is experienced in gluing a metal surface to papers and the like for the reason that amaterial which will -adhere readily to papers vwill not zo adhere to the metal.

It is a further object of my invention to so pre are the metal that the adhesive material Y,wil readily adhere to the surface.

, -"Vlith these and other objects in view the present invention consists in the combination and .arrangements of parts, as will be hereinafter more fully described, 'shown s in the accompanying drawings, and particularlypointed out in the appended claims.

In. the drawings, Figure 1 is aview in elevation of a sheet of metal rou hened for the receipt of adhesive material. ig. 2 is an end view ofthe sheet of metal shown at Fig. 1. Fig. 3 'is an end view of the metal sheet show- 3 5 ing one coating of adhesive thereon. Fig. 4

is an end'view of the metal sheet showing two coatings of adhesive thereon. Fig. 5 is a view in elevation of a sheet of metal ,with a portion only of its surface roughened for the '4o'l recei t of adhesive.' Fig. 6 is an end view of ,the s eet shown at Fig. 5. Fig. 7 is an end "view ofthe sheet shown at Fig. 5,/with two coatings of adhesive applied to the ortion of the surface which is roughened. 1g. 8 is an end view .similar to Fig. 4,.with a fabric covering a portion of the adhesive surface. Figs. 9,10,11, 12, 13, and 14 show some of the va rious forms in which my improved clip may be made. Fig. 15 shows the end of an en- 5o velop to exhibit some of the methods of using my 1m v'roved cli Fig. 16 is a fra' mentary view o several s /eets of paper hel together by one of my'improved clips, which is anothermethod of usmg.

Application median a, 1905. senil No. 253.428.

Like characters of reference designate corresponding parts throughout the several views... g d.

In the preferred embodiment of my invention I take a sheet of metall, from which a number of my improved clips may be cut, as 6c on the lines 2 2, androughen one surface with an abrading materialor-in any ap roved manner. Upon the roughenedv lsu ace is spread a coating, preferably composed `of water, dextrin, acetic acid,glycer1n, and, sul- 65. fate of aluminium. The proportions which I prefer to use are as follows :v Water, ftysix per cent.; deXtrin, sixteen per cent. ,'race y tic acid, eight per cent-,- glycerin, sixteen perl s cent., and sulfate of aluminium, four dper cent. 7o

After applying a coating ofthe sai composition. .thoroughly dry such coating and then apply upon the said coating 3 a second coating 4 of t e same composition.

For some purposes it is found desirable to roughen but a portion of the surface of the sheet 1, as shown at Figs. 5 and 6, and to apply to the said roughened surface two coatings ofthe adhesive composition, as shown at Fig. 7, thereby rendering but a ortion of 8o the c 'p adhesive. It is also foun desirable at-times to cover a portion of the adhesive surface with paper or other fabric, as shown at Fig. 8, accomplishing thereby a result simiv"lar to coating but a portion of the surface with adhesive.

My improved cli I may be made in any desired form, some o which are shown in Fig.

9 to 14, inclusive.

I have shown at Fig. 15' two of my clips', as 9o 6 and 7, secured by their adhesiveto the flap 8 of an envelop, and the clip 7 isshown as 1t will appear bent about the edge. I have also shown a clip 9 secured to the envelopby its v adhesive and assed through an eyelet 10 in 95 theflap 8 and bent tofretain the a in a closed position. ,The said clip 'may a so be used to close thefla of an envelop, as at 11, by adherin to both the envelo -body and the iiap. have illustrated at IFig. 16 anroo other method of using my improved clip, wherein the clip is secured to the corner of a Asheet of pa er and other sheets being placed thereon. he corner of the sheets andtheattached clip are rolled, as shown at 12.

While I have given above the referred ingredients and their proportions or the adhesive coating applied to my clip, it is found desirable to vary the proportions for use in different tem eratures and localities, and it is even foun desirable to omit some of the ingredients for accomplishing the same or similar results. l

While I havle described my process lof making my clip as'roughening a sheet from which the clips'are'cut, 1t is obvious that the clips ma be cut rst and roughened afterward.

While I have found it desirable to apply two dpatings of the adhesive material forthe.

reaso'that the first coating applied and'dried isf'notsov readily affected by the moisture a plied, it is obvious that' a'single coating on y' ma beused. v v.

t willl be'A understood that the thickness ofthe several materials of coating is greatly exaggeratedin the drawings for cle'arness of illustration. y

k'Having thus described my invention, what I claim as novel, and desire to secure by Let` ters Patent, is-

1. A clip `for holding papers and the like, comprising a piece of sheet metalhaving a coating of adhesive on its surface.

2. A clip for holding papers andthe like, comprising sheet metal having its surface roughened and on the roughened surface a coating of adhesive.

3. A clip for holding papers and thev like comprising a strip of flexible sheet metal having lts surface roughened and on the roughened surface a coating capable of becoming adhesive by the application of moisture.

4.4 A clip for ho ding papers and the like comprising a stri of sheet metal having its surface roughene and on the rou hened surface a coating capable of adhering thereto and on'the coating a second coating capable of becoming adhesiveA by, the applicati'oniof moisture;

5. A clip comprising a strip of fleXib e metallifa'vingl a roughenedfsurface, on the r'ougheiied surfface' a coatlng of adhesive anda fabric secured thereto by the adhesive and covering a por'- tion of the adhesive surface. A y l In, testimony whereof I affix my signature in presence of two witnesses. l
